What happens if an arrhythmia is detected?

If the abnormal source of an arrhythmia is detected, the physician may use the opportunity to perform treatment such as radiofrequency ablation. Radiofrequency energy from the tip of the catheter is used to heat and destroy the heart cells that are creating the arrhythmia.

 

Some reasons for having an EP study include fainting, irregular heartbeat, and a very fast or slow heartbeat.
